Theories

This lesson could be done in 1 period. Students should have access to computers for this lesson. I would partner students up for this lesson.

Activity: Acids vs. Bases

This lesson could be introduced by asking the following question:

• What are the differences between an acid and a base?

Students would then have to find the answer. Students should record the answers to the questions posed in their notes.

As students finish and verify their answers with you, they can be introduced to the following questions:

• What is the difference between the Arrhenius and Bronsted-Lowry theories of acids and bases?
• What limitations are there to the Arrhenius Theory? (looking for 3)
• What is a conjugate acid-base pair?

Students can work at their own pace and whatever is not finished, can always be finished at home.

Students should then be given the following practice questions, to practice how to identify conjugate acid-base pairs.

Practice: Conjugate Acids & Bases
